Availability of 15" x 7" Rims for 2020 Airstream

Question

Question:

My travel trailer came with 15x7 rims. 6x5.5 bolt, 4.25 center and 0 offset. Can’t find these anywhere! It’s a 2020 airstream. Any advice?

Hi Joe,

We don't have any 15" x 7" rims with that bolt pattern right now but I know they exist. If you can send me a picture I can try to determine what you have exactly and see if they're something we can add from one of our manufacturers. You could also contact Airstream directly, they should have information on what wheels came with the trailer. Is this for a spare or are you trying to find a replacement?

Just a spare. I’m running 225/75 15’s endurance e rated. I’ve been told I could run a 15x6 wheel - that endurance will fit on it. Thoughts?

@Joe that is part of the reason why I asked. Since it is just a spare you could go with the 15x6. If it was going to be a regular replacement wheel you were driving on all the time I would say look for the same size so they match.

Thanks very much, Robin. I am going to pull one of the existing wheels off the trailer and check the backside of the rim to see exactly what I’m dealing with. Once I do that, I will get back to you.

Thank you for providing that picture. It is true that your typical #11 Torflex axle has a capacity of 4,100-6,000 lbs. However, your axle is in fact a #11 Torflex despite the 3,500 lb capacity. This was confirmed by Dexter. The correct lift kit for…

Hey Bryan, that's a good question. The pricing can definitely be misleading, but I wouldn't use it to judge the quality of the tire. A lot of that comes down to promotions, inventory, and whether you're looking at a tire by itself or…

The 5.30-12 tires, being wider, are going to make more contact with the road. This means that the noise, and heat build up will be higher than a 4.80-12 tire but the rolling resistance will actually be less because the tire is larger diameter. The…

The difference between an load range C and load range D tire in the same size is the capacity and psi rating. The two tires will still have the same dimensions and fit on the same wheel. The D rated tire has a higher capacity. For a ST175/80D13 like…

Answer 12

The two sizes you mentioned are pretty similar and fit many of the same 15 inch wheels. The 205/75-15 fits rim widths of 5 inch to 6 inch whereas the 225/75-15 fits widths that are 5 inch to 6-1/2 inch. The 205 is 27.1 inches tall and the 225 is 28.4…
